public virtual byte[] GetKeyAlgorithmParameters();
abstract member GetKeyAlgorithmParameters : unit -> byte[]
override this.GetKeyAlgorithmParameters : unit -> byte[]
Public Overridable Function GetKeyAlgorithmParameters () As Byte()

返品

Byte[]

バイト配列としての X.509 証明書のキー アルゴリズム パラメーター。

例外

CryptographicException

証明書コンテキストが無効です。

例

次の例では、 GetKeyAlgorithmParameters メソッドを使用して、証明書のキー アルゴリズム パラメーターをバイト配列として返し、コンソールに表示します。

using System;
using System.Security.Cryptography.X509Certificates;

public class X509
{
    public static void Main()
    {
        // The path to the certificate.
        string Certificate =  "Certificate.cer";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);

        // Get the value.
        byte[] results = cert.GetKeyAlgorithmParameters();

        // Display the value to the console.
        foreach(byte b in results)
        {
            Console.Write(b);
